If the catalytic converter is bad, you would fail emission.
Performance would be affected with higher fuel consumption.
In time to come, it would clog itself due to its inefficiency in producing the heat necessary to burn of unburnt fuel from the engine.
I would suggest getting a free scan done at your local Autozone outlet and provide me with the exact error code to understand the situation better.
